y ing and severing mechanism for making plated Work thereon. One object of my inl vention is to provide simple 'and comprehensive means for manipulating the plating yarn fingers and cutter from the main pattern chain. Another object is to produce mechanism which is simple, accurate and easily adapted for changes of pattern.

For purposesV of illustration my invention is shown and described embodied in a seamless yhosieryn machine of the Well-known Scott & Williamstype though I do not limit the application of my invention to that type.

In making striped Work by plating it is preferable to feed the plating yarns to the needles at a point on the needlecircle in advance of thethroat plate, butin timed relation with the throat plate yarn, in order to produce fancy -patterns such as vertical stripes and dots by means of manipulation of` the needles. ,My invention relates to ma` chines adapted to perform such Work. It is necessary to cut off the plating yarn Within a short space of time after its removal from the needles and it is another purpose of my invention to cause this cutting at the proper interval after the removal of the yarn.

In theexample-shown in the drawings the usual pattern chain 85 turns with the sprocket Wheel 84 on the pattern chain shaft 80, and,`

through lugs on the right side of the pattern chain causes the main pattern vdrum 120 to be racked .around irregularly under its control by the train of gears 122, 121, 123 (Fig. 11). The lugs on the pattern chain 85 acting through the controller 83 lower the pawl 82 on the segment gear to rack the Wheel 81,4

shaft and drum 120 as desired-all as described in the patent to Robert W. Scott 1,152,850 dated September 7, 1915. The chain itself is racked every four revolutions of the needle cylinder by a pawl 87' mounted on the segment gear 75. The segment gear 75 and the main pattern drum 120 turn on a shaft 76.

There are the regular yarn lingers F pivotcd on the cross pin 554 on the latch ring 550, adapted to feed yarn at the throat plate 559. The latch ring 550 is pivoted at 552, as usual, tothe bracket 401 mounted on the bedplate D of the machine. For the purpose of lifting these regular yarn fingers out of action the usual thrustfbars 460 areprovided, passing downwardly through an upper arm 463 on the bracket. l101 and the. lower comb 451 on the stud 450, to the mainl pattern drum 120.

'throat plate 559.v For the purpose of liftwhere they are acted on by Suitable rings of drum cams 501 and 502.

In addition to the regular yarn fingers F,

ing the auxiliary yarn finger Fa entirely out of action when knitting portions of the stocking Where striping is not desired, a special thrust bar 570, controlled from the mai-n patthrust bars460 is pivoted to' the auxiliary, i. yarn finger Fa at such apoint that when av cam tern drum inthe same manner as the usual 4 v ,501 or 502 on the main pattern drum 120 comes in contact with the thrust bar, the auxiliary yarn linger is lifted out of action.

At the point on the needle circle where the auxiliary or plating yarn is fed, the needles are raised to various levels in order that striping can be obtained by varying the feeding level of the auxiliary yarn and allowing the yarn to float behind the needles to which it is not fed.-

While other patterns can be made with more yarn lingers, l have shown a machine using one auxiliary yarn finger, and one main yarn linger to produce vertical and horizontal stripes and dots in the resulting fabric. To produce such a pattern by these means the needles can be separat-ed 'into a plurality of levels at the auxiliary feeding point by means of jack 380. In the machine shown in the drawings the needles on which the vertical stripes are to be knit are jackless; those where the dots are to occur have medium length jacks; and the remainder have long jacks (Figs. 5 and 6). y

l have discovered that the feeding level of the auxiliary yarn linger can be varied for striping purposes by lugs' on the left side of the pattern chain links through mechanism which will be described presently. Vhen it,

is desired to feed the plating yarn to all the needles having jacks, no lug is used on the left side of the pattern chain to raise the auxiliary yarn finger from its lowest position. When the plating yarn is to feed to only the long jack needles aflo'w lug is used. `When the plating yarn is not to be fed to any of the needles, for a short space of time, there is a high lug on the pattern chain to lift the auxiliary finger out of action.

` The level at which the auxiliary yarn finger feeds the yarn is determined by the position of a notched lever cam 585 pivoted on the stud 609 carrying the yarn cutter actuating lever 611. This lever cam 585 has a long quick sloping surface against which an adjustment screw 586 on the auxiliar)7 yarn linger rests when the yarn linger is in its lower feeding position (Figl) and it also has a notch or shoulder on which the screw rests when theyarn is in its higher feeding' position- (Fig. 2). When it is desired to temporarily lift the auxiliaryyarn linger entirely out of action during striping, the lever cam 585 is turned up until the adjustment screw 586 on the yarn finger rests on a long surface above the notch (Fig. 3). The lever cam hasa depending 'arm engaging against a set screw 588 in the upper `end of a bell crank operating lever 589 which is mounted` on the bedplate Dof the machine by means of a bracket. This set screw 588 can be used to adjust any irregularities in the vertical position of the auxiliary yarn finger. There is a spring 587` fastened to the lever cam tending to hold the depending arm against the upper arm of the bell crank lever. It

should be'noted that owing to the connection between the set screw 588 and depending arm it is still possible` to lift the latch ring.

The exact position of this operating lever ing striping bracket 232 pivoted on a stud 234 on the frame of the machine. The lower end of the vertical rod 231 is fastened to the horizontal` arm 233 by a screw 239 playing in a slot 240 in the rod. The movements of the bracket. 232 are under the cont-rol of the pattern chain through the medium of a depending arin 235 having a pin 236 overlying the left side of the pattern chain links (Fig. 10). ln this way pattern chain links having low or high lugs on their left side are availed of to raise and lower the auxiliary yarn finger Fa.

It will be observed that by means of the mechanism which has been described, both `the needle cylinder and the auxiliary yarn linger are actuated in timed relation to the segment gear. The movements of the auxiliary yarn linger are so timed with relation to the revolutions of the needle cylinder' that they always occur at the same wa-le in the knitted fabric and, if desired, these changes can be made to occur a. little previously to the changes of the main yarn lingers -F thus bringing the changes of the auxiliary yarn linger at approximately the same wales of the knitted fabric as the changes caused by the main yarn lingers.

The mechanism already described can aetuate the auxiliary yarn finger every four revolutions of the needle cylinder or at longer intervals if desired and the dots or horizontal stripes can be varied at will by changing the links on the pattern chain. Each pattern chain link corresponds to twelve courses on the stockingl or twelve revolutions of the needle cylinder, and each link is racked every four courses, three racks to the link. Therefore there are three lug-positions on each link. I also provide tripping means by which the auxiliary yarn linger can be made to change its position at shorter intervals than four revolutions. This Vmechanism includes a latch 237 pivoted on the vertical rod 231 near its lower end and adapted to engage the upper side of the horizontal arm 233 of the tilting bracket 232. and a trip rod 241 therefor. The points of pivotal connection of the pattern chain, pawl 87, and the trip rod 241 to the segment gear 75 are such that for the most part ,the p'awl and rod move in opposite directions, and the trip rod has aV longer movement than does the pattern chain pawl.

, its lower feeding position when the latch is tripped by pulling the vertical rod 231 downwards.` lVhen the latch is set on the upper side of the horizontal arm 233 the vertical rod and the horizontal arm are positively `pivoted together with the screw 239, which links thev vertical rod with the horizontal arm of the bracket, at the lower end of the slot 240 in the vertical rod. Means by which' the aforementioned trip rod 241 .disengages the latch from the horizontal arm 233 and allows the spring 238 to pull the vertical rod down comprise a trip'wire 242 carried by the latch 237 which can be ad'usted at such a height that the'free end o the trip rod 241 will engage itslower end'and push the latch clear of the horizontal arm. The'trip rod 241 may be of fiat bar material set on its 'narrow edge in order that the lower end of the trip'wire 242 can be engaged by the trip rod when lthe tilting bracket vhas been raised by either a high or a low lug on the pattern chain. vThis adjustment is shown in Figs. 3 and 10. It should be observed however, that the trip wirel can, if desired, be-

set at such a level that the trip rod will trip the latch only when the bracket has been tilted by a high lug on the pattern chain; and intthat case the trip rod will miss the Wire when the tilting bracket is raised by a low lug -(Fig. 2). It will be seen that inf this way the machinecan be adjusted to produce dots and Ahorizontal stripes each four courses wide, dots four courses wide and horizontal stripes two courseswide, or dots and hor1zonta1 stripes v -eah two courses wide, as desired. By varying the adjustment of the trip rod other combinations can be obtained, but it is believedthat the combinations above mentioned will be adequate for ordinary practical purposes.

F or cutting oii'suchyar' s as are removed from the knitting, a usuril circle toward the -fr'on't ofthe machin-e.A It will be noted that outgoing yarns must be carried around the circle for a considerablel distance from the auxiliary feeding oint or the throat plate before the last need e on which the yarn was knit comes closest to the cutter 608. My invention provides for cutting the outgomg. yarns when the yarn has been thus brought around through an angle.

which, in the case of an auxiliar yarn, is 280 degrees. One of the regular irust bars 46()c is'used to actuate the yarn cutter 608' by means of the lever 611,- the cutter being controlled from the main pattern drum 120 except vduring striping.' When it is desired to sever yarns during striping, the yarn cutter is operated from a continuouslyY mov-v j clamp 606and- -cutter 608 are provided inside the needle of actuating the cutter 608. The cams can be so positioned on the gear that the cutter shears every second revolution of the needle cylinder in timed sequence to the yarn finger -movements as above described. The cam movements are brought to the thrust bar 460c by ain operating lever 592 pivoted on the bedplate of the machine by a bracket 593, aconnecting link596 and a bell crank lever 594 pivoted on the lower comb 451.

These cutter operating means can actuate i the yarn cutter thrust bar only when the tilting bracket 232 'connects them together. On the tilting bracket is a vertical arm 582 with a wire link 583 passing throu h an' eye in its upper end, the other end o the link being hooked to a dog 581 pivotally hung on the yarn cutter thrust bar.` Mounted on this Wire link on opposite sides of the eye of the vertical arml 582 are adjustable collars 584', and vbetween the collar on the side towards the dog and theeye of the vertical arm is `a spring 584 which tends to hold the toe of the ,dog over thebell crank operat- -ing lever. The wire link and its collars and to which ribbed tops are transferred, means must be provided for levelling off the needles in order to effect this transfer. This operation includes a change in the position of the lower jack cam 366 (Figs. 7, 8 and 9) and lill! `ilo -I propose to do this by lowering the point v of the jack cam 366 to the position shown in dotted lines in Figure 7 by a connection With the well-known instep needle raising and lowering-cam or so-called switch ca1n,. The lower 'ack cam 366 is mounted inside the cam ring 2 1 and consists of a low stationary base 366u and a point 366" adapted. to slide vertically in va groove on the cam ring side of thebase. The butts of theA 'acks 380 are long enough to be acted on by t e point 366. This movable point is secured to a slide or support 209 moving in avertical slot milled part way through the cam ring 271.. On this slide 209 is a pin 210 passing through the slotnin and projecting out of the cam ring 271. This pin is moved vertically by the point of operating finger 211 mounted .in the base of the switch cam bracket 411. This operating finger 211 isoscillated by a winged collar-212 secured thereto which engages against a depending'arm 214 on a switch cam lever 408. The winged collar 212 is held against the depending arm 214 of the switch cam lever by a tension spring 213l in such 'a position that when the switch cam 415 is raised I The slot 412 is so shaped that when the switch cam is turned upward the screw 413 forces the spindle and cam towards the needle butts. The switch cam isv operated by cams 509 and 510 on the main pattern drum 120. These cams are all in one path on the drum, that numbered 509 being low, and that numbered 510 being of full height. The switch cam is connected to its drum cams by the abovementioned lever 408A which has a wing 409 mounted on t-he rear end of thespindle 410 with the win g overlying a vertical gravity rod 216. The gravity rod passes down through an opening in the bedplate D and is linked to one end of a lever 215 pivoted on a stud 124 projecting from the frame of the machine, the other end of this lever projecting into the path of the above-mentioned drum cams.

During they striping on the 'leg 4of the stocking the point 366b of the lower jack cam' is raised to its full height in order that the medium, and long jacks 380 may give the necessary separation of the needles N at the auxiliary feeding point; The point 366b of the lower jack cam is held in this position by the switch cam which at this time is at' its full heightf-until the heel is reached, when the switch cam drops to its lowest position by the lever 215 riding olf one of its drum cams 510, and the point of thejack cam is lowered. The consequent failure of the jacks tocause separation of the needles at the auxiliary feedingpoint at this time is immaterial since no striping is being made during reciprocating knitting' of the heel. Vthen at the end of the heel the switch cam is -raised to bring the instep needles down into action again, the switch cam raises the point of the lower jack cam to operative position and the separation of the needles at the auxiliary feedingpointisresumed. Similarlytheswitch cam and the point of the lower jack cam are lowered during the toe. Coming off the toe the switch cam and the poi-nt of the lower jack cam are raised once'more. The switch cam drops to an intermediate point by means of the lever 215 coming onto its drum cam 509 at the time thatthevstocking is to be pressed ofi'. This movement of theswitch cam from` its highest position to its intermediate position is sufiiclent to cause the point of the lower jack cam to drop to inoperative position, thus eliminating the yseparation of the needles at the auxiliary feeding point land permitting levelling off of the `needles for transfer ur- `without at the same time causing the long butt needles to be raised by reason-of the switch cam being put in its lowermost position. The mechanism which I have described permits the .switch cam to move to its lowermost position, when desired, without re uiring the point of the lowerjack cam to crop any further than is permitted when the switch cam is in its intermediate position. (The operation of the point of the lower jack cam islnot in any way varied by the operations which are now to be described). y

Assumingthat the machine is to make a pattern consisting of a four course horizont-al stripe; four courses during which only vertical stripes are to be made, four courses containing vertical stripes and dots, and four courses containing only vertical stripes, the operation of the mechanism is as follows.

The first horizontal stripe is started by a rack ofthe pattern chain 85 which racks the main pattern drum 120 causing thev special auxiliary yarn finger thrust bar 570 and the mainplating yarn: finger thrust bar 460 to ride ott' .their cams 502 and dro-p their lingers into action. At the same time the main yarn fingers F whichwere feeding yarn are withdrawn from action by cams on the main pattern drum.V The same racking of the pattern chain which causes this change of the auxiliary and main yarn ingers also brings a high lug on the left side ofthe pattern chain under the pin236 of the tilting bracket 232. This tilts the bracket t0 its highest point (see Fig. 3) at the saine timethat the main pat-tern drum is racked, thus keeping Y the auxiliary yarn finger in inoperative position, and leaving the yarn from the main yarn finger tobe knit in alone, and forming the horizontalV stripe. The tilting of the 4bracket to its highest point as described also causes the dog 581 on the thrust bar 460 to project over the bell crank lever 596. The cams 591'on the gear 65 are so positioned with relation to the movements of thev pattern chain that at the proper time within the first revolution after the tilting of the bracket 232, one of the cams will cause the bell crank lever 594 and the thrust rod 460 to be actuated, opening and closing the yarn cutter 608 in timed sequence as already described. The

. chain as the last needle tof whichthat yarn was fed comes near the cutter. t

. Atthe end of four courses the pawl 87 will again rack the pattern chain 85 and the pin 236 on the depending arm of the bracket will drop olf the high lug onto a portion of a link which has no lug on it (sec Fig. 1). The dog 581 thereupon withdraws from engagement with the bell crank lever 594, disengaging the yarn cutter from its operating means. Simultaneously the'y tilting bracket 4 allows the auxiliary yarn finger-to drop to vwith vertical stripes only,I

its'lower feeding position (Fig. 6) where its ad] usting screw 586 rests on the long low slope of the notched lever cam 585. In this posi-- tion the auxiliary yarn linger feeds yarn to all the needles having jacks but not to the jackless needles. As these jackless needlesl come to the clearing cam 360 (Fig. 7) they Vare raised slightly in the usual manner and this auxiliary yarn is floated behind the jackless needles, thus forming vertical stripes. At the end of four courses the pawl 87 again racks the pattern chain and the bracket 232 is tilted to the'posit-ion shown in F ig. 2 by 'a 10W lug on the left side of the patternI chain.

ln this position the auxiliary yarn finger is raised to its upper feeding position and the auxiliary yarn is fed only to the needles having long jacks (Fig. 5). This causes the yarn to be floated in back of not only the needles bn which the vertical stripes are being made lbut also the needles on which dots are desired.' The adjustment of the wire link 583 vwli'en making the fabric now being described is such that the tilting of the bracket l232 by a low lug on the left side of the pattern chain does not cause the dog 581 to engage the bell crank lever 594:. v

After making four courses with the striping mechanism in this position the racking of the pattern chain causes the pin 236 to drop olf its low lug onto a portion of a link havingno lug and four courses are knitted as p-reviously descried. The pattern can be repeated as desire When the leg of the stocking has been iinlished the cams 501 will be racked under the foot of the .yarn cutter thrust bar 460 and the auxiliary,l yarn finger thrust bar 57 0 liftingl themy out' of actlon; Iandn'any --desired change in the arns fedbythe main yarn fingers F 'will ge accomplished in a `similar manner. At the'end 'of-fthe' heel the yarn `cutter and the auxiliary yarn iin er thrust bar rideoithe cam 501 and strlping will continue through the foot underV the influence of lugs on the left side of: the pattern chain. At the end of the foot Ithrust bars 460 and570 will again be raised, this time by the cam-502 and these cams will keep the auxiliary yam finger out vof action until When it is desired to vary the pattern I whose manufacture has just been described by making the horizontal stripe only two instead of four courses wide, the 'tripping means are adjusted and brought into play in the manner which will now be described. The trip wire 242 is mounted in the latch 237, and for the particular pattern just mentioned the lower hooked end of the trip wire should be' adjusted at the level shown in Figs. 1 and 2. With this adjustment the trip wire willnot be affected by the trip rod when the tilting bracket is on no lug or a low lug, the lower hooked 'end of the wire lying below the rod. When the auxiliary yarn linger is raised to inoperative position` and a horizontal stripe is being made (Fig. 3) the hook i such manner that at the end of the' second course after t-he rack of the pattern chain which 'brought the tilting bracket' and trip mechanism to the position of Fig. 3, the trip rod will hit the lower end of the trip wire and free the latch 237 on the upper side of the horizontal arm 233. `The spring 238 thereupon pulls the vertical rqd 231 ownwardly, tilting the bellcrank operating lever 589 away from the lever cam 585 and return: ing the auxiliary yarn linger to its `lewe/r feeding position where it resumes feeding to all needles having jacks. In this way the knitting of courses having only vertical stripes is resumed after two courses. At the end of two more courses the pattern chain will be racked again, and the tilting bracket will drop olf the high lug onto a portion of a link where there is no lug, thus setting the latch on the horizontal arm'233. The knitting ofthe pattern will then .continue as in the previous pattern.

It' it is desired to further vary the pattern whose production was described above by not only makin the -horizontal stripe two courses-wide ut also by reducing the number of courses in which the dots appear the -trip Wire 242, should be set at such a height that the trip rod 241 will en ge same when the tilting bracket is raised y either a high or a I termediate Iposition by a low lug and `two courses are made in which the auxiliary yarn is brought-behind both the jackless and the medium jack needles. The trip wirejbeing opposite the lower part of the end of the trip rod 241 that trip rod will trip the latch at the end of these two courses and the auxiliary yarn finger will resume eedin 1r to all the needles having jacks. At vthe end, of two the pattern can be repeated as many times as desired by insertion `of the proper links on the pattern chain. Y

It should be noted that there is no 'difiiculty about timing the striping patterns with relation to the other operations of the machine since the pattern indications are placed directly on `the continuously racked pattern chain carrying all the other pattern indications. It should be further noted that this pattern chain is racked steadily and in time with the article being knit, in distinction to the pattern means ordinarily used for controlling striping mechanisms.
